This study examines the seismic performance of slender Air Traffic Control (ATC) towers in high‑hazard regions (PGA > 0.4g), where vertical taper, torsional eccentricity, and top‑heavy cab mass can significantly increase drift, base shear, and collapse risk relative to conventional buildings. Existing studies often rely on linear procedures and outdated provisions, leading to underestimation of nonlinear behaviour and limited guidance for ATC towers designed to SNI 1726:2019. The research aims to quantify these irregularity effects and formulate design recommendations that satisfy Immediate Occupancy, Life Safety, and Collapse Prevention performance targets. The methodology couples response spectrum analysis, using a site‑specific Padang spectrum consistent with SNI 1726:2019 and ASCE 7‑16, with nonlinear pushover analysis interpreted through FEMA/ATC performance‑based criteria. A parametric study is performed on three cab configurations small, medium, and large modelled as 5%, 15%, and 25% mass ratios at the tower head, while keeping a 10 m × 10 m hybrid core–frame shaft constant. Results indicate that larger cab mass produces systematic but moderate increases in global displacement, story drift, and base shear, while plastic hinges localize primarily in the upper stories and cab‑support region, yielding performance levels from Immediate Occupancy to Collapse Prevention. Overall, the tower meets code drift limits and acceptable performance if local strengthening is provided around the shaft–cab interface, offering a calibrated reference for top‑heavy ATC tower design in Indonesian high‑seismic settings and identifying priorities for future time‑history and soil–structure interaction studies.

This study aims to compare two methods of raw material inventory management, namely Economic Order Quantity (EOQ) and Periodic Order Quantity (POQ), in improving efficiency and reducing operational costs at Konveksi Arey Hijab. The main problem faced by this company is the irregularity in raw material inventory management, which causes wasteful costs, especially ordering costs and storage costs. Based on raw material purchase data in 2024, which recorded a total purchase of 26,203 kg with a total cost of IDR 1,834,573,300, this study uses a descriptive quantitative approach to compare the two methods. The results of the study show that the EOQ method produces lower inventory costs, namely IDR 16,568,074, compared to the POQ method. The application of the EOQ method can reduce the frequency of excessive ordering, while the POQ method is more effective for ordering periods that are adjusted to seasonal demand. This study recommends that Konveksi Arey Hijab adopt the EOQ method to optimize raw material inventory management, reduce wasteful costs, and improve the company's operational efficiency.

The problem that occurs in Medan city is the existence of riverside slum settlements, one of which is Aur village. The irregularity of buildings, high building density level, and the quality of buildings and facilities and infrastructure that do not meet the requirements for adequate housing can affect children's development. This research aims to explore children's activities in riverside slum areas. The research method used is exploratory qualitative, namely in the form of interviews and observations. The results of the research show that children spend their time in the afternoon playing and reciting the Koran around Masjid Jami Aur. This shows that the mosque and its courtyard are an important space for children's activities.

A thalassemia is a group of inherited blood disorders characterized by decreased or absent production of hemoglobin. Symptoms of thalassemia vary greatly from patient to patient but may include anemia, fatigue, and susceptibility to infections that can plague their quality of life. Therefore, a detailed evaluation of the serum biomarker profile in thalassemia patients is necessary to elucidate its effects on the body. This study was performed to define the serum biomarker profile. This study aimed to evaluate the serum marker levels among 100 thalassemic patients and compare them with their physiological ranges. Blood urea (B.UREA), serum creatinine (S.CREAT), aspartate aminotransferase (AST), alanine aminotransferase (Alt), alkaline phosphatase (ALP), total serum bilirubin (TSB), serum uric acid (S.U.A), triglycerides (TG), cholesterol (CHOL), albumin (Alb), serum calcium (S.CA) and Carbohydrate Antigen 15-3 (CA15.3) were analyzed comprehensively as key indicators in this study. The test showed that B. UREA's mean number was 24.33±0.8805, which was safe within normal limits. So, no abnormal results were found for this indicator in our tests despite the fact that others showed irregularity. The means of the values measured by S.CREAT, AST, AlT, AlP, TSB, S.U.A, TG, CHOL, AlB, S.CA, and CA15.3 were respectively, 0.8109±0.2007, 28.93±3.325, 26.1±2.698, 101±13.64, 3.261±1.978, 12.78±8.951, 146.8±87.2, 147.5±22.89, 67.94±44.7. This study makes valuable contributions to the field by elucidating the serum biomarkers of individuals with thalassemia and presenting changes in some markers compared to normal levels. However, further research is required in order to investigate the clinical significance of such alterations.2, 9.392±0.4079, and 42.08±7.275.

Background: Magnetic resonance imaging (MRI) is a cross-sectional imaging technique based on the principle of magnetic resonance of hydrogen atoms due to radio frequency (RF) signals with the same frequency as the precession frequency (lamor frequency). MRI at the beginning of its development used a semiconductor magnetic field with a power of 0.5-1.5 Tesla, but now MRI uses a superconductor magnetic field with a power of 1.5-3 Tesla. One of the advantages of brain MRI in epilepsy cases is that it can display clear information about the anatomy and pathology of the head in general in the temporal lobe area. The use of 3D sequences with isotropic voxels such as SPACE (Sampling Perfection With Application Optimized Contrasts With Varying Flip Angle Evolution) is very useful for generating images with high resolution, thinner cuts, and multi-level reconstruction can be performed in several fragments that allow the acquisition of 3D sequences at one time. Methods: The type used is descriptive qualitative research with a case study approach by conducting interviews with 2 radiology specialists, 1 neurology specialist and 3 radiographers related to MRI brain examinations with clinical epilepsy in August-September 2023 in the Radiology Unit of Prof. Dr. I. G. Ngoerah Denpasar Hospital. G. N. G. Ngoerah Denpasar. Results and Conclusion: This study used five (5) patient data who had clinical epilepsy. Based on the results of observations, interviews and documentation in the radiology unit of Prof. Dr. I.G.N.G. Ngoerah Denpasar Hospital, it can be seen that the procedure for examining MRI Brain with clinical epilepsy is that there is no special preparation, only filling out inform consent. The patient is positioned supine on the examination table with a head fixation device with a head first body position and hands beside the body. Radiographers put the patient into the gantry by setting the isocenter i n the middle of the glabella. After positioning the patient the radiographer sets the parameters using axial T2 Turbo Spin Echo (TSE), sagittal T2 Turbo Spin Echo (TSE), coronal T2 Turbo Spin Echo (TSE), axial T2 Turbo Spin Echo (TSE) dark fluit, axial T1 Turbo Spin Echo (TSE) axial Diffusion Weighted Imaging (DWI) and Susceptibility Weighted Imaging (SWI) and coronal T1 SPACE IR isotropic sequences.In addition, the role of coronal slice T1 SPACE sequences is to clearly see the presence of partical dystrophy, to see the thickening or irregularity of the cortex cerebri clearly. In addition, it is also to see the calcification of the temporal lobe and to measure the volume of the hippocampus.

WHO in 2018 noted that of the 675 million elderly deaths in the world due to degenerative diseases, 225 million (33.33% proportion) were in developed countries and 450 million (66.66 proportions) were in developing countries. The elderly population is estimated at almost 600 million people, which is projected to be 2 billion in 2050. Problems that often occur in the elderly include physical changes: cell decline, changes in the cardiovascular system, decreased respiration. Efforts to improve the health status of the elderly in the community are through Posyandu services for the elderly. Utilization of Posyandu for the Elderly is low even though it provides the benefits needed for the health of the elderly. This study is an analytic observational study with a cross sectional approach to analyze whether or not there is a relationship between knowledge and attitudes of the elderly with the use of posyandu for the elderly. The elderly population in Ujung Labuhan Village, Namorambe District, Deli Serdang Regency in 2021, as many as 72, the sample was taken by purposive sampling with a total of 45 elderly. Data analysis using chi square test. Most of the respondents have a low level of knowledge, namely 26 respondents (57.8%), a small proportion have good knowledge, 19 respondents (42.2%). Most of the respondents had a positive attitude towards the elderly posyandu as many as 23 people (51.1%), a small number of respondents had a negative attitude as many as 22 people (48.9%). Based on the results of the chi square test, it is known that the value of p = 0.000 <0.05 means that there is a relationship between attitudes and the use of posyandu for the elderly. There is a relationship between knowledge and attitudes of the elderly with the use of posyandu for the elderly. The elderly population in Ujung Labuhan Village, Namorambe District, Deli Serdang Regency in 2021. It is hoped that health workers will take a more innovative approach in providing health services to the elderly while still implementing health protocols.

Problems related to illegal downloading are still a problem for songwriters or musicians in Indonesia. In the UUHC and the ITE Law, it has also been regulated regarding the protection of copyright infringement through the internet media. In fact, the enforcement of this law is less firm. Based on the explanation given to the description above, this research is entitled "Legal Protection for Songwriters on Internet Media (Sociology of Law Studies)." The formulation of the problem of this research is how the legal protection for songwriters on the internet media, how is the responsibility of the free Mp3 song download service provider against copyright infringement through the internet media for songwriters, public perception regarding the protection of songs circulated on the internet media. The approach method used in this research is sociological juridical. The research specification was carried out by descriptive analytical. The method of presenting data in this study was carried out by direct interviews with the community or filling out questionnaires on the internet. The analysis used in this paper is qualitative. The results show that the legal protection of songwriters has been automatically protected by UUHC, the government has also made efforts to block illegal song download sites but in reality people still download illegal songs on the internet, the responsibility of free song download service providers, in the development of copyright infringement through Internet media is usually charged to the Internet Service Provider (ISP) if the provider provides facilities that allow copyright infringement to occur. Site providers have actually become an irregularity, these sites have shifted their position from being an illegal site to a legal site by positioning themselves as a song search site, the song provider in this case has violated the law. Public perception about individuals who download songs are wrong because they violate the Copyright Law. The public is aware of copyright infringement, but according to facts on the ground, people still download songs without permission. This behavior is carried out because the protection of songs by the Government is not strong enough. There are no strict sanctions for providers of free songs on the internet and free song downloaders on the internet.   Keywords: UUHC Protection, Download Songs, Service Providers on Internet Media
